Although I found certain parts of the book edifying, there were just too many problems for me to give a high rating. Most of the faults stem from DeHaan's dispensational reading of scripture and his desperate attempts to force certain texts to conform the events of his day (the book was originally published in 1963) to the Bible's prophetic message. Particularly outrageous was his assertion that the translation of Enoch before the Flood prefigured man's conquest of space, thus providing evidence that in 1963 the return of Christ was right around the corner. After all, Enoch had to zip through space in order to reach heaven, thus making him the first astronaut! So we can see that just as in the days of Noah when there was a man in space (Enoch), we have men in space also which means that God's judgement is at hand. Oh boy.
On the other hand, there is enough interesting information and a true evangelical concern in DeHaan's book to render it moderately helpful for a small number of readers. Unlike many of today's date-fixing, money-raking paper backs that litter the shelves of the Prophecy sections in Christian bookstores, DeHaan appears more sincere in his presentation, obviously loves Christ, and puts forward enough helpful material to make The Days of Noah somewhat worth while for casual reading. I also appreciated the opportunity to learn more about the faulty system of dispensationalism from a sincere source, reminding me that the kingdom of God includes many who live outside of Reformed orthodoxy.
